Jupiter was the first of the Sun's planets to form, and its inward migration during the primordial phase of the Solar System affected much of the formation history of the other planets. Jupiter's atmosphere consists of 76% hydrogen and 24% helium by mass, with a denser interior.
Resonance in Jupiter and Saturn's orbits moves Neptune out into the Kuiper belt. Late Heavy Bombardment occurs in the inner Solar System. [2] 800 million years 3.8 bya: Oldest known life on Earth. [81] [142] Oort cloud reaches maximum mass. [84] 4.6 billion years Today: Sun remains a main-sequence star. [117] 6 billion years 1.4 billion years ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
1979 – Voyager 1 flies by Jupiter and discovers its faint ring system, as well as volcanoes on Io, the innermost of its Galilean moons. [201] 1979 – Voyager 2 flies by Jupiter and discovers evidence of an ocean under the surface of its moon Europa. [202] 1980 – Voyager 1 flies by Saturn and takes the first images of Titan. [203]
This timeline of cosmological theories and discoveries is a chronological record of the development of humanity's understanding of the cosmos over the last two-plus millennia. Modern cosmological ideas follow the development of the scientific discipline of physical cosmology .
Jupiter might have shaped the Solar System on its grand tack. In planetary astronomy, the grand tack hypothesis proposes that Jupiter formed at a distance of 3.5 AU from the Sun, then migrated inward to 1.5 AU, before reversing course due to capturing Saturn in an orbital resonance, eventually halting near its current orbit at 5.2 AU.
Half of Jupiter's households earn at least $105,413, much higher than Florida's median of $69,303. Here's the breakdown. The city boundaries for Jupiter as seen here on a U.S. Census Bureau web page.
This is a timeline of astronomy. It covers ancient, medieval, Renaissance-era, and finally modern astronomy. It covers ancient, medieval, Renaissance-era, and finally modern astronomy. Antiquity
